feat(mobile): WIP redesign core app surfaces

[t3dotgg]

Warning

WIP: This redesign is still under active visual verification.

What Changed

• Modernizes the mobile composer into one stable surface with a restored attachment action, a direct model selector, compact configuration access, and keyboard-safe expanded geometry.
• Rebuilds model selection as a searchable provider-grouped sheet with device-local favorites, selected-state feedback, and the mainline legacy-model fold.
• Simplifies the phone thread header so the title stays readable, status remains distinct, and secondary terminal, files, git, and review actions live in one menu.
• Refines the thread list, new-task flow, approval cards, and multi-question input while preserving current mainline pinning, provider metadata, and connection-state behavior.
• Shows only actionable thread states. Completed or already-read threads fall back to timestamps instead of a persistent Done label.

Why

The previous React Native surfaces were too small, crowded important titles with utilities, and produced an unreliable composer when the keyboard opened. This update brings the mobile client closer to the rebuilt native direction while keeping the implementation shared across iOS and Android.

UI Changes

Captured from the repository's iPhone 6.9 iOS simulator workflow.

Simulator evidence: baseline run and final WIP run.

Verification

• 74 focused mobile tests pass across model selection, preferences, home, thread-list, connection-state, and header behavior.
• Targeted lint passes for every changed TypeScript file.
• GitHub Check, Test, Release Smoke, Effect Service Conventions, and Mobile Native Static Analysis pass on the latest commit.
• The final iOS workflow validated 15 dark-mode screenshots across iPhone 6.9, iPhone 6.5, and iPad 13.
• Local mobile package typecheck is blocked by an unchanged packages/contracts error already present on main: orchestration.ts reports a message property on Option<unknown>.

Checklist

• Rebases onto current main
• Preserves the mainline legacy-model fold
• Includes before and latest simulator screenshots
• Covers phone and tablet layouts in the simulator matrix
• No animation or timing behavior changed, so no video is required

Fixed pending card inset height

Medium Severity

Feed bottom inset for pending approval or user-input overlays uses hardcoded heights (270 and 430) instead of measuring the redesigned cards. Tall approval details or multi-option input steps can exceed those constants and leave messages hidden under the overlay.

Approvability

Verdict: Needs human review

This is a major mobile UI redesign introducing new components (ModelPickerSheet, thread header status), new features (model favorites), and significant changes across core app surfaces. The WIP designation and an unresolved bug report about hardcoded overlay heights warrant human review.

Note

🤖 GPT-5.6 Sol responding on behalf of Theo

We're closing this PR as we clean up the T3 Code backlog. Thank you for taking the time to put this together.

This is an explicit work-in-progress redesign of the home header, composer controls, model sheet, thread list, and related mobile components. The 27-file visual change has no selected final design that can be reviewed as one finished behavior.

If you believe we closed this in error, please reopen the PR and leave a comment explaining what we missed.
